.lepresentsga casing, adapted to support f f bearingsfin thev casing]A The bearingsfsupefff .1 05f `rlv` through apertures in, `the casing. closed by l l ll'jithespindles' 'arereplacedibefore anyof-'thein l/Vithin casing in superiniposediposifm tion are placed a pair of gears j and 7c, the lower gear having one hundredteeth, the upper gear f: having an eXtra orhunt'- ing tooth, that is, having one hundred Vvand one teeth, and both gears being in mesh with a worm Z on the shaft h. The lower gear j is fixedly secured to a dial m which is adapted to revolve with the gear, while the upper gear L is connected toa ldial'n, concentric with dial mf, by means of a spring-pressed annular detent oy adapted to engage in depressions-in the under side of the dial fn, whereby the dial fn, maybe revolved by the gear 7e and at the same time maybe turned relative to the dial m withoutrevoh'ing gear k.

.Between the dialsm andm'and adjacent the periphery Vofdial n., is placed a ring p recessedlas atg, Fig. 2, and supporting in the recess a spring-pressed Vpivoted stop 1' one endof which isnormally retained eX- tended beyond 'the periphery of the ring and is adapted to contact with a lined stop or pin s on dial n and'stop relative movement of 'the dials whenA the dial n. is moved clockwise or to give andpermitpin s to pass when dial n is turned counterclockwise. The wall of the ring p forms an internal gear t adapt-ed to be engagedby a pinion u secured vto dial m by means of Va pin o, the head of which Vis slottedpermitting its rota- 'tion by means ofa screw driver with consequent rotation vofthe pinion which results in rotation of ther-ing p enabling.V the stop@a to be positioned, forthe purpose to'be hereinafter explained. Y

The gears andV lials are centered about a pin fw, being spaced from the bottom ofthe casing by a washer mand secured-by a nut g/. @n the upper surfaces of theV dials m and n are drilled holes e, la', respectively, which, when they are aligned, are adapted to receive a pair of pins 2, 2', depending from a U-shaped member 'which embraces an arm Ll. and is pivoted thereto Aadjacent its outer end. The inner end of ar1n4'islsecured to a forked lever 5, which in turn is pivotally carried by brackets 6.A A spring 7, secured 'at one end to member 3, wrapped around a post4 8 on member 3 and engaging a vpest 9 on arm et, acts to keep member 8 in line with arm 4:, but yieldingly `permits he member to swing on its pivotal connection with the arm. A second spring 10, an end of which bears on the forked lever 5, is wrapped around the pivot lconnecting the lever with brackets 6 andV tends to move the lever 5, arm 4 and member 3 with its 'depending pins downwardly.

Pivotally supported between its ends on the pivot.supportingv Vthe forked lever 5V is a lever 11, one end of vwhich underlies lever 5, Fig. 3, and the other end of which is adapted, under the influence of a spring :21, to engage in a reduced section of a rod 12 slidably supported in brackets 13 and carrying atits end a member 14'adapted to cooperate with a knife 15. A spring 16 surrounds the rod12 and Vacting between one of the brackets 13 and a ,collar 17 secured to the rod tends to move the rod to effect the shearing of athread between the member 14 and knife 15, when the arm of lever 11 is withdrawn from the reduced section of the rod 12.

Secured at one end to the collar 17 on rod 12 by slotzand pin connection is a link 18, theotheriend yof which is pivotally connected to one arm'ofV ay leverf19 pivoted tothe cas ing. The oth'errarm of lever 19 has secured to it a. piece ofrubber 20, which .is adapted, when the rod 12 is released and moved under the action ofspring 16, to be moved by the turning of lever 19, through link 18, into contact with wheel Z and act as a brake thereon.

ln the device as above described, the wheel d is made so that its perimeter measures three inches, or, in other words, that in the passage over it of one yard of thread it will make twelve `revolutions. The worm on shaft e andthe worm wheel on shaft /L are in the ratio Vof 29C to- 1A so that the shaftv h willmake one revolution to every twentyfour revolutions ofzthe shaft e and wheel d. rlhe worm Z is asfone hundred to one and as one` hundred Aand one to one with the gears jV and lc, respectively. Therefore, for each one. hundredrevolutions of the shaft L, the

gears 4j and cwill ma-ke one revolution, but since the gearif; has one more tooth than the gear j', it will lag behind the gear j, or in other words, two points one on each gear, or-on the dials m and n driven by the gears,

Yif in line when the gearsstarted would be out of line when they had made one revolut1on,or, conversely, two points out of line by a distanceV equal to one tooth would be in line-after one revolution of the gears, since 0'ear c will make a distance of one tooth less Athan one revoluti-on vwhen gear y' makes one fullrevolution. rlfhe size of the wheel l andthe ratior between the worm and gear on the vshafts c and/7L being given the dials m and nare calibratedso that when it is desired to utilizeV the device for measuring yarn-or thread -being wound, the dials may be: initially'vrelatively adjusted so that the holes e, e will-be out of line a distance equivalent to one or more teeth on the gear Zc,which, having one more tooth than gear y', willf1i1reach vrevolution ofthe dials lag behind gear 'c a distance equal to one tooth andbring the holes in line after one or more lrevolutions of the gears and dials.
